Applications of Pipette It facilitates the even distribution of cells in cell seeding and avoids foaming and bubble formation. Improved ergonomics minimizing the risk of repetitive strain injuries, as there's no plunger to press down to move the piston, and no need to twist knobs or the plunger to adjust the volume. Use of Pastettes in Microbiology Applications In addition, they are used to carefully reactivate reagents to create density gradients, such as a phycoline gradient that is used to purify plasma cells. After three of his children died of typhoid before reaching adulthood, Pasteur began searching for treatments and cures of various diseases in both men and animals.
